Momentum and heat transfer in a power-law fluid with arbitrary injection/suction at a moving wall

The momentum and heat transfer in the laminar boundary layer of a non-Newto nian power-law fluid flowing over a flat plate, which is moving in the dire ction opposite to the uniform main stream, and with arbitrary fluid injecti on/suction along the plate surface, are analyzed. The partial differential equations are decomposed into a sequence of ordinary differential equations using the Merk-Chao series to obtain universal velocity and temperature fu nctions that are independent of the fluid injection/suction distribution pr ofile. Results are tabulated as a function of the problem parameters. Frict ion coefficients and Nusselt numbers are calculated for constant fluid inje ction/suction along the plate.
